Should I get an iPad Air with 16 or 32 GBs of storage to be used primarily for school?

trying to decide on 16 or 32 storage for ipad. This will not be primary camera, not for music or movies. Used for school apps, Quizlet, etc. But will need to download schoolwork to home printer, will we be able to do this easily with a a 16GB generation 4 or Air?
